Recovery Pt. 5 — Bloodwork

Subjective markers like mood, motivation, soreness, and energy are all real signals and worth monitoring. But they lag, and they are easy to rationalize. Bloodwork cuts through that noise.

The minimum useful panel for performance monitoring includes cortisol, testosterone, and the cortisol-to-DHEA ratio. Cortisol is not the enemy; it is supposed to spike in the morning and in response to training. The problem is chronic elevation without adequate recovery, which the ratio helps identify. A widening cortisol-to-DHEA ratio over time is a more reliable indicator of systemic overload than any single cortisol reading in isolation.

For those wanting to delve deeper with a broader panel: inflammatory markers like TNF-alpha and the neutrophil-to-lymphocyte ratio, along with glutamine and the glutamine-to-glutamate ratio, reflect systemic stress and gut integrity under heavy training load. These require specific requests, not standard inclusions, but for those pushing the edges of their recovery capacity, they provide information a basic panel misses.

Timing matters as much as the markers themselves. Cortisol fluctuates significantly across the day, making a single reading difficult to interpret without context. Measuring at multiple points daily, and consistently across training blocks, is far more informative than any isolated snapshot.

Quarterly bloodwork at a minimum; semi-annual for the deeper inflammatory markers. The goal is not perfect numbers; it is to establish your own baseline across training phases and recognize when markers trend in the wrong direction long enough to demand a response.

Bloodwork won't tell you what to do. But it will tell you what is true, and that is where good decisions start.
